Self-similarity Analysis of Cartographic Lines and the Automated Line Generalization

By discussing the self-similarity and fractal dimension of cartographic lines,the features of cartographic lines in shape are quantitated and extracted,and a new automatic generalization method for cartographic lines is proposed.This method has a good effect on maintaining the shape features,quantization and modelization of the proceducre of cartographic generalization,and provides a new solution to some problems difficult to solve with other methods in the automatic cartography.
